Argon plasma coagulation in Barrett's esophagus

Argon plasma coagulation (APC) is noncontact electrocoagulation technique that creates tissue damage. Recently, it has been reported that Barrett's esophagus and Barrett's adenocarcinoma in situ could be successfully managed by APC. The aims of this treatment are to prevent the developing of adenocarcinoma and to promote the restitution of normal squamous epithelium. Combined antireflux surgery or proton pump inhibitor therapy are indispensable to this treatment. Shorter length of Barrett's epithelium and normalization in pH with PPI treatment were the independent predictors of sustained long-term restitution of squamous epithelium. In patient with Barrett's esophagus, APC offers an effective, minimally invasive alternative to other treatments previously performed.     

Long-term follow-up and factors predictive of recurrence in Barrett's esophagus treated by argon plasma coagulation and acid suppression

BACKGROUND AND STUDY AIMS: In several series, argon plasma coagulation (APC) combined with acid suppression has led to short- or medium-term eradication of Barrett's esophagus. The present study was designed to assess the long-term outcome after this treatment. PATIENTS AND METHODS: 39 patients with Barrett's esophagus, seven of them with low-grade dysplasia, underwent APC and received 40 mg omeprazole daily for eradication of the metaplastic epithelium. After the treatment period, patients were randomly assigned to receive 20 or 40 mg omeprazole daily for long-term acid suppression. Histological and endoscopic changes were evaluated annually. Univariate and multivariate analyses were used to test the following 10 variables as predictors of sustained reversal of Barrett's esophagus at the end of follow-up: age, gender, length of diseased segment, presence of hiatal hernia, circumferential nature of lesion, presence of low-grade dysplasia at initial biopsy, number of coagulation sessions, result of pH monitoring under protein pump inhibitor (PPI) treatment, omeprazole dosage, and initial response to therapy (after 1 month). RESULTS: The median follow-up period was 36 months (range 12 - 48). The endoscopic and histological relapse rates at 1, 12, and 24 months, and end of follow-up were, respectively, 30 % and 44 % (12/39 and 17/39), 57 % and 54 % (16/28 and 15/28), 60 % and 57 % (17/28 and 16/28), and 62 % for both rates (23/37). According to multivariate analysis, shorter length of diseased segment and normalization of pH with PPI treatment were the only independent predictors of sustained long-term re-epithelialization. Among the seven patients with low-grade dysplasia, four experienced relapse after 1 month, and during the long-term follow-up, one was lost to follow-up and all the others experienced relapse, but only one developed low-grade dysplasia again. Cancer was found in two cases after 12 and 18 months, respectively. CONCLUSIONS: Persistence of acid reflux and greater length of diseased segment are the major factors associated with a high relapse rate after successful initial reversal. APC for ablation of Barrett's esophagus cannot be recommended.     

Barrett食管的治疗研究及p53在治疗前后的表达

目的：研究不同方法治疗Barrett食管（BE）患者的疗效，并通过检测治疗前后食管中p53的表达改变．探索各种治疗方法产生效果的可能机制。方法：经胃镜及活检确诊的BE患者75例，随机分为5组进行治疗。（1）对照组（A组），不进行特殊治疗；（2）抑酸药组（B组），口服奥美拉唑20mg，每日2次。（3）胆汁吸附剂组（C组）．口服铝碳酸镁1000mg，每日3次。（4）抑酸药＋胆汁吸附剂组（D组），口服奥美拉唑及铝碳酸镁，用法用量同B、C组。（5）氩气凝固术（APC）＋抑酸药及胆汁吸附剂组（E组），在D组治疗基础上对BE患者行内镜下APC治疗。各组均治疗3个月。治疗前、治疗后1个月及3个月后观察并记录临床症状及内镜下表现，取得食管黏膜组织标本行病理学检查．并采用SABC免疫组化染色检测食管上皮中p53的表达情况。结果：3个月后各治疗组的症状均较治疗前明显减轻，与A组相比均有统计学差异（P〈0．05）；各治疗组间相比，症状缓解率无明显差异（P〉0．05）。内镜检查发现。A、B、C、D组的BE黏膜均未见明显变化，而E组能使91％的患者BE黏膜消除。D、E组治疗后食管p53表达均较治疗前显著降低，与A组相比有统计学差异（P〈0．05），E组改变比D组更显著。各治疗组均未发现严重不良反应。结论：抑酸药和（或）胆汁吸附剂不能使BE逆转，但可消除临床症状并可改变BE中p53的表达。APC＋抑酸药及胆汁吸附剂方案可以消除症状。也可消除BE黏膜。安全性好，可降低p53的表达，是治疗BE的一种合理可行、有效实用的方法。p53的表达可作为判定治疗效果的可能指标。     

Intraepithelial high-grade neoplasia and early adenocarcinoma in short-segment Barrett's esophagus (SSBE): curative treatment using local endoscopic treatment techniques

BACKGROUND AND STUDY AIMS: In recent years, short-segment Barrett's esophagus (SSBE) has attracted increasing attention in the context of reflux disease. However, there is continuing controversy regarding its potential for malignant transformation. PATIENTS AND METHODS: Between October 1996 and September 1999, 50/115 patients (43 %) with intraepithelial high-grade neoplasia or early Barrett's adenocarcinoma, who underwent local endoscopic treatment, had developed a malignant lesion in an (SSBE). In the framework of a prospective observational study, 28 patients were treated with endoscopic mucosal resection (EMR), 13 with photodynamic therapy, and three with argon plasma coagulation; six patients received combinations of these treatments. RESULTS: Complete local remission was achieved in 48/49 patients (98 %). One patient switched to surgery after the first EMR, because there was submucosal tumor infiltration, and in one patient out of 50 local endoscopic treatment failed. A mean of 1.7 +/- 1.4 treatment sessions was required for local endoscopic treatment. The method-associated mortality was 0 %. The rate of relevant complications (stenosis, bleeding) was 6 % (3/50 patients). No cases of severe hemorrhage (Hb fall >2 g/dl) or perforation occurred. During a mean follow-up period of 34 +/- 10 months, metachronous intraepithelial high-grade neoplasms or early adenocarcinomas were seen in 11/48 patients (23 %), who received further successful endoscopic treatment. Four patients died during the follow-up period, but in only one patient was this due to his Barrett's adenocarcinoma (this was the patient who underwent esophageal resection). CONCLUSIONS: The malignant potential of short-segment Barrett's esophagus must not be underestimated. Organ-preserving local endoscopic treatment shows good acute-phase and long-term results. Local endoscopic treatment represents an alternative to esophageal resection in the case of intraepithelial high-grade neoplasia and selected early adenocarcinomas in Barrett's esophagus.     

Local treatment of early cancer in short Barrett's esophagus by means of argon plasma coagulation: initial experience.

In recent years endoscopically controlled local therapeutic methods, such as photodynamic therapy, mucosectomy, or laser therapy, have been used with a curative aim for the destruction of early esophageal or gastric cancers. We report on our experience of treating histologically proven mucosal cancer in Barrett's esophagus with argon plasma coagulation (APC), in three patients. All the mucosal esophageal cancers, with a mean diameter of 4 mm, were successfully destroyed after one or two treatment sessions. Additionally, in two of the three patients the specialized columnar epithelium was replaced by normal squamous cell epithelium when APC treatment was combined with omeprazole. In the third patient with Barrett's esophagus, a partial squamous cell re-epithelialization was induced. No method-related mortality and morbidity were observed. During the mean follow-up of 24.3 +/- 1.1 months (range 23-25 months) one tumor recurrence developed which was successfully treated with photodynamic therapy. In patients with small early Barrett's carcinoma APC might offer an effective, minimally invasive alternative to mucosectomy or photodynamic therapy, as the treatment procedure is less cumbersome and the equipment less expensive.     

Esophageal complications of gastroesophageal reflux disease: presentation, diagnosis, management, and outcomes

The esophageal complications of gastroesophageal reflux disease include peptic esophageal erosion and ulceration, peptic esophageal strictures, and Barrett's esophagus. Endoscopy is the diagnostic procedure of choice for the initial evaluation of lesions. For most patients, symptoms can be controlled with proton pump inhibitor (PPI) therapy. PPIs are also highly effective for healing esophageal erosions and ulcerations and for preventing recurrence of peptic esophageal strictures. Because Barrett's esophagus predisposes individuals to esophageal adenocarcinoma, these patients are advised to have regular endoscopic surveillance to detect early, curable neoplasms.     

Une cause rare d’hémorragie digestive: la polypose gastrique induite par inhibiteur de la pompe à protons au long cours

Proton pump inhibitors are responsible with gastric polyps’ development. Generally asymptomatic, their proliferative and inflammatory properties may trigger a digestive hemorrhage.We report the rare case of a 73-year-old man treated by a long-term proton pump inhibitor for a gastro-esophageal reflux disease. Gastrointestinal bleeding and iron deficiency anemia require a gastroscopy which reveals diffuse glandulocystic and hyperplastic gastric polyps. After a polypectomy therapy failure, an argon plasma coagulation treatment of the most inflammatory polyps is processed. The proton pump inhibitor is stopped and the control gastroscopy done one month later does not find any inflammatory polyps.This case report is a chronic digestive hemorrhage due to gastric polyposis secondary long-term treatment by proton pump inhibitor.This case demonstrates the efficiency, the simplicity of a treatment by argon plasma coagulation compared to treatment by polypectomy. The case also shows the polyposis regression after stopping proton pump inhibitors and introducing a treatment by histamine H2-receptor antagonists.     

Circumferential endoscopic mucosal resection in Barrett's esophagus with high-grade intraepithelial neoplasia or mucosal cancer. Preliminary results in 21 patients

BACKGROUND AND STUDY AIMS: Treatment by endoscopic mucosal resection (EMR) has been established for early lesions in Barrett's esophagus. However, the remaining Barrett's esophagus epithelium remains at risk of developing further lesions. The aim of this study was to evaluate the efficacy of circumferential endoscopic mucosectomy (circumferential EMR)s in removing not only the index lesion (high-grade intraepithelial neoplasia (HGIN) or mucosal cancer), but also the remaining Barrett's esophagus epithelium. PATIENTS AND METHODS: A total of 21 patients were included in the study (11 men, 10 women), who had Barrett's esophagus and either HGIN (n = 12) or mucosal cancer (n = 9). Of the patients, 17/21 were at high surgical risk and five had refused surgery. On the basis of preprocedure endosonography their lesions were classified as T1N0 (n = 19) or T0N0 (n = 2). The lesions and the Barrett's esophagus epithelium were removed by polypectomy after submucosal injection of 10-15 ml of saline; a double-channel endoscope was used in 15/21 cases. Circumferential EMR was performed in two sessions, the lesion and the surrounding half of the circumferential Barrett's esophagus mucosa being removed in the first session. In order to prevent the formation of esophageal stenosis, the second half of the Barrett's esophagus mucosa was resected 1 month later. RESULTS: Complications occurred in 4/21 patients (19 %), consisting of bleeding which was successfully managed by endoscopic hemostasis in all cases. No strictures were observed during follow-up (mean duration 18 months) and endoscopic resection was considered complete in 18/21 patients (86 %). For three patients, histological examination showed incomplete removal of tumor: one of these underwent surgery; two received chemoradiotherapy, and showed no evidence of residual tumor at 18 months' and 24 months' follow-up, respectively. Two patients in whom resection was initially classified as complete later presented with local recurrence and were treated again by EMR. Barrett's esophagus mucosa was completely replaced by squamous cell epithelium in 15/20 patients (75 %). CONCLUSIONS: Circumferential EMR is a noninvasive treatment of Barrett's esophagus with HGIN or mucosal cancer, with a low complication rate and good short-term clinical efficacy. Further studies should focus on long-term results and on technical improvements.
